Ghostly Neutrinos Illuminate the Milky Way's Bubbles ⚡ экспресс
Picture this: at the heart of the Milky Way, an enormous bubble popped—not of soap, but of searing plasma. This 'blast' blew out two gigantic expanding balloons. Now, researchers have snagged neutrinos (ghostly particles) from their shock fronts, nailing down that our Galaxy is a master at turbocharging particles to mind-blowing energies. What other tricks might the cosmic 'volcano' at the galaxy's core be hiding?
Millions of years ago, the black hole at the center of the Milky Way hurled out scorching gas, inflating two colossal bubbles. Their edges are shock waves that compress matter. The IceCube detector, frozen into the Antarctic ice, has for the first time caught neutrinos from these walls. Neutrinos are ghostly particles that barely interact with matter. In the bubble walls, shock waves accelerate protons to enormous energies; colliding with gas, they spawn neutrinos that travel to Earth, passing through the Galaxy almost unhindered. This proves that the bubbles are natural particle accelerators and reveals the black hole's stormy past. The outburst that created them was a million times brighter than a supernova. If we could see gamma rays, these bubbles would shine in the night sky brighter than a hundred full Moons.
🎯 Neutrinos are so elusive that billions of them stream through your body every second, yet only a few will ever interact with you in your lifetime.
🎬 Neutrinos in Arthur C. Clarke's novel '2010: Odyssey Two' foreshadowed a catastrophe on Jupiter, while the real particles told us about an explosion in the heart of the Milky Way.
